Episode notes
Contextual Comments
- Write code comments that explain the "why" behind the code, not just the "how".
- Focus on business logic and context, not obvious code functionality.
Overly Opinionated Libraries
- John Gregory needed a JSON schema parsing library for code generation but found none suitable.
- Existing libraries had private functions, preventing customization, forcing him to write his own.
Library Design
- When designing libraries, consider how others might use them in unintended ways.
- Offer options and avoid being overly prescriptive, allowing for flexibility and extension.
